I almost posted this in the physics forum but I realised that what I am ultimately looking for is a type of substance to use, and the way it behaves will be down to its chemical make-up.
I am not a scientist, my only knowledge is from tv documentaries. I am an animator working on a personal project and I wanted to film some liquids interacting.
My problem is that I want to film the same type of turbulence as what you see when you pour milk into a cup of tea. The problem is that the turbulent forms which the milk makes are on a scale far too large for the effect I am aiming for, I need the same effect but much more detailed, with intricate micro scale vortices.
This is where I get stuck, I dont need the effect to have depth, it can be a surface effect, like the turbulence on the surface of a soap bubble, but the problem is that it has be on a scale which complies with the FOV of my camera and the distance it focuses at for super macro. This means the area I have to work with effectively is about 10 x 10cm.
Any suggestions on the types of liquid mixtures I can use to get extremely detailed turbulence effects would be great, I was thinking that the viscosity of the liquid would play a major role, the temperature too.. I think the rainbow-like streaks you see in puddles from diesel are also an option, but they need to have very specific lighting to be filmed effectively..
Give me some suggestions and feel free to ask me to elaborate further if you need to!
I've just been in the chartroom and got some great suggestions from Schroedingers_hat to help me understand what I'm looking for. Its immiscible liquids, but which ones would be best, I am not sure.. Also I had pearling agent suggested to me and organic liquids..
